Twitter unveils tool to share tweeting locations

SAN FRANCISCO (AP) - Twitter can now let the world automatically know your whereabouts as well as your thoughts and activities.

A new feature unveiled Thursday gives Twitter users the option of including their location with the assorted musings posted on the Internet messaging service.

Locations won't be included unless users turn on the tracking tool. The technology, which shadows people through Web browsers, can be turned off at any time.

Twitter is responding to the growing popularity of other Internet services, such as Foursquare and Loopt, that broadcast people's locations. Facebook is expected to join the trend soon, too.
